1, external leakage blocking the vast, easy to control leakage, the use of safety

Internal and external leakage is a risk factor for safety. Other automatic control valves usually extend the stem from the electric, pneumatic, hydraulic actuator to control the rotation or movement of the spool. This should solve the long-term movement of the valve rod moving seal leakage problem; only the solenoid valve is with a magnetic force on the seal in the electric control valve is separated from the core magnetic casing to complete, there is no dynamic seal, so the leakage is easy to block the vast. Electric torque control valve is not easy, prone to internal leakage, or even pull off the stem head; the electromagnetic valve leakage within the structure type is easy to control, until reduced to zero. Therefore, the use of special safety valve, especially suitable for corrosive, toxic or high temperature media.

2, the system is simple, then the computer, the price is low

Solenoid valve itself is simple structure, the price is low, compared to other types of control valves and other types of actuators are easy to install and maintain. More significant is the composition of the automatic control system is much simpler, the price is much lower. Because the electromagnetic valve is a switch signal control, and industrial computer connection is very convenient. In today's popularity of computers, a sharp decline in the price of the times, the advantage of the electromagnetic valve is even more obvious.

3, action express, power is small, the shape is light

Solenoid valve response time can be as short as a few milliseconds, even if the pilot solenoid valve can be controlled within tens of milliseconds. Since the self into a loop, more sensitive than other automatic control valve. The designed solenoid valve coil power consumption is very low, is an energy-saving products; also can be done just trigger action, automatically maintain valve position, usually do not power consumption. Electromagnetic valve small size, not only save space, but also light and beautiful.

4, the adjustment precision is limited, the application of the medium is limited

Solenoid valve is usually only two states, the spool can only be in the two limit position, can not be adjusted continuously, so the adjustment accuracy is also subject to certain restrictions.

The solenoid valve on the media have high requirements for cleanliness, including granular media can not be applied, the case must first filter out impurities. In addition, the viscous medium can not be applied, but also, the specific range of viscosity of the product is relatively narrow.

5, model variety, wide range of uses

Although the inherent electromagnetic valve, the advantages are still very prominent. So we designed a variety of products, to meet the different needs, extremely versatile. Solenoid valve technology advances are centered on how to overcome the congenitally deficient, how to better play to the inherent advantages and expand.
